Once the type of motion law of oscillating rod,the motion angles Φ 0、Φ′ 0 of push travel and return travel and the allowable pressure angles [α]、[α] r are being adopted there will certainly exist a maximum value ｛ψ m｝ max of travel angle ψ m of oscillating rod;once the type of motion law of oscillating rod,the travel angle ψ m of oscillating rod and the allowable pressure angle[α]、[α]r of push travel and return travel are adopted,there will certainly exist the minimum values｛Φ 0｝ min 、｛Φ 0′｝ min of motion angles Φ 0、Φ 0′ of push travel and return travel.The solving method to ｛ψ m｝ max and ｛Φ 0｝ min 、｛Φ 0′｝ min presented in this paper possesses certain guiding significance to the analysis and design of spherical cam mechanism.
